Hello Sandra. I am Ken Middleton, son of Sarah Blumson born 1898. I have also researched the Blumson line and have gone back a couple more generations beyond Fanny and can say with certainty that this Blumson line originated in Wellingborough, Northamptonshire with Robert Blumson,born 1709, and Susanna Newman, both of whom married in the Fleet prison in 1738 having had permission to travel to London, the authorisation being signed by Roberts Uncle, a Thomas Blumson who was then a village elder. More if you are interested. Regards, Ken.
